PLC programming is an electronic system for digital operation. It uses programmable memory to store the instructions for executing logic operation, sequence control, timing, counting and arithmetic operation, and control various types of machinery or production processes through digital and analog input and output. The following is a summary of learning experience of PLC programming.

The learning experience of PLC programming is summarized as follows. I hope friends in industrial control have better ways to add:

1. Have a certain electrician foundation —- master the use of sensors, proximity switches, encoders, pneumatic components and other common devices and the control principle of relays.

2. Re learn the number system and number system conversion —— master the concepts of binary, octal, hexadecimal, BCD code and ASCI code.

3. Select the PLC brand of the flow type in your region as the model for learning——— After learning, you can better connect with the actual work.

4. Buy a laptop (dual core or above with a configuration of no less than CPU, 1G memory, 80G hard disk, and serial port) – a necessary tool for learning and working outside.

5. Learn basic computer operations, such as power on/off, file saving, and basic applications of WORD and EXCEL office software (computer users must know); Installation and uninstallation of common software (such as the installation and uninstallation of programming software); Typing (used for program naming and commenting).

6. Look for PLC programming software, simulation software and teaching software (of course, learn to use them)—– Necessary learning tools.

7. Buy relevant books and video textbooks—– Learning materials.

8. The PLC programming manual, user manual and use cases can be collected online or obtained by participating in the product promotion meeting—- Materials that will definitely be used in the work

9. After the above preparations, you can learn PLC by yourself. Generally speaking, the basic instructions of PLC ladder diagram are easy to learn, and its logic relationship is connected with the relay control schematic diagram. But the function instruction is much more difficult.

10. It is better to go to a school with strength and good reputation for training—– Compared with self-study, it can shorten the learning time, learn more systematically, and make more teachers and classmates for future development.

11. Get to know more peers, PLC manufacturers and agents around by all means, so as to get their help and useful information.

12. Insist on learning, communicate with peers and practice more—– Programming is highly integrated with theory and skills, so we should read more books and practice more to improve programming technology.

13. When you go out to contract projects, you should also prepare this type of PLC program decryption software —— because sometimes you will forget the password added in your own program, and sometimes it is someone else’s encrypted program. The customer wants you to re optimize it, add new functions, modify parameters, and delete the original scheduled shutdown program. This is why many people find decoding software.
